14 Claims.

An object of the invention to provide a ma- 1' w chine which will beadjustable for the winding of solid continuous ring cores of anydiameters between the minimum and maximum diameter limits of themachine, and which will also wind such rings with any desired size,gauge or type of 35 wire or other winding material, ranging for instancefrom one mill to inch flat ribbon wire in the case of rheostats, andfurther to provide for an infinite variation of pitch or leads withinthe minimum and maximum limits of the mam) chine, ranging for instancebetween 15 to 3000 turns or convolutions to the ring.

Another object is to provide a machine of this character which will beextremely accurate in operation and in predetermination of the de- 25sired winding, will be rapid in operation, and

will not require highly skilled operators for tending to the machine.

In winding rheostats great precision is necessary so that the windingwill be evenly spaced 30 with the proper pitch or lead between theturns,

and the windings must be sufllciently tight upon the ceramic core sothat they will lie flat upon the core surfaces and will not becomedisplaced.

Inaccomplishing this there must be a tension or pull upon the wire as itis being wound suflicient to bend the wire sharply about the corners ofthe core at the same time pulling it in flat re-" lation to the coresurfaces, and itis an object of the invention to provide means wherebysuch 4 tensionai pull may be provided, and which may be the size ofring, wire and pitch) before respooling the bobbin.

It is further proposed to provide bobbin respooling means by whichbobbins may be respooled' during the winding of the rheostats, andfurther to provide counter means in connection, with the respoolingmeans to predetermine the amount of wire wound on the bobbin, therebyeliminating waste of wire through the spooling of short lengths.

' leads, and tensions for different sizes and character of wires. Inparticular it is proposed to pro vide pitch adjusting means which can beset to a predetermined pitch before the winding operation starts, or ifdesired can be changed even while the machine is in operation. It isproposed in connection with the tension adjusting means tq provide acalibrated dial on the winding shuttle by which the proper tension maybe pre determined and maintained.

With the above and other objects in view, an embodiment of the inventionis shown in the accompanying drawings, and this embodiment will behereinafter more fully described with reference thereto, and theinvention will be finally pointed out in the claims.

In surrounding relation to the top flange 26 of the post 26 there isprovided a cover plate 31 of ring shape, having a slot 32 disposed atthe rear in alignment'with the slot 23 of the post 26, the innerperiphery of the'plate 31 being spaced from the outer periphery of theflange 23 thereby providing a circular slot 33. i I

The plate 3| is mounted upon a segmental circumferential wall 34extending from one wall of the slot 32 to a point in spaced relation tothe forward central point of the plate 3|, upon a segmental wall portion35 extending from the other wall of the slot 32 to one of the pair of asegmental wall portion 36 extending from the forward line of the gibs36-36 to a point spaced from the'forward central point of the plate 3|.the segmental wall portions 34, 35 and 38 being secured to the base l3by means of bolts 39, which bolts also secure the cover plate in place.

A ring gear supporting bearing wall comprises two segmental sectionsarranged within'the wall portions 34, 35 and 33, one segmental section40 extending from the right hand-side of the slot 32 to the forward lineof the gib members 3636, and the other segmental section 4| extendingfrom the left hand side of the slot 32 to the side edge of the righthand gib member 36 and in flush relation to the end of the wall portion35. The wall sections 63 and are secured to the .base l3 by means ofsuitably spaced screws 42.

The wall sections 40 and 4| are provided at their inner peripheries withupwardly projecting flanges l3 and II, respectively, forming an annularbearing for the inner periphery of a worm ring gear mounted upon thewall portions 46 and II, this ring gear being supported upon a series ofradially disposed antifriction rollers 46 disposed in pockets 6" in saidwall portions and secured against longitudinal displacement by setscrews 41 engaged upwardly in the wall portions 40 and ll, and havingstuds 48 at their upper ends engaging annular grooves 49 in the rollers.

The ring gear 46 is provided at one point with a projecting pin 56 whichoperates an automatic mechanism for stopping the machine at a pre- 76provided in their inner peripheral surfaces with slots i through whichthis pin moves. The shank of the pin 50 is threaded and may beselectively engaged in one or the other of three threaded holes 58 and5|) provided in the ring to vary the point at which it actuates thestopping mechanism. Its degree of projection may also be varied byscrewing it in or out to secure fine adjustment of its actuation point,as will hereinafter more fully appear.

A radially disposed arm 52 is secured to the ring gear 45 by means ofscrews 59, the inner end of this arm extending beneath. the slot 33where it is provided with a square hole 54 .for interlocking engagementtherewith of the clamping means of the ring to be wound, it beingunderstood that as the ring gear is rotated the clamping means isrotated and rotates the ring,

, the ring being rotatably supported upon the post 2t, and which ringsupporting and clamping means will be presently more fully described.

The plate M is provided at its forward central portion with arectangular cut-out 55 and the base plate I3 is provided with a pair ofparallel T-slots 56-55, and within which cut-out and slots the drivingworm for the ring gear and its supporting bearing is mounted. A slidemember 51 having a pair of spaced bearing standards 58-58 at its upperside is provided at its lower side with a pair of T-bars 59-59 engagingthe T-slots 56-56 of the base it, the bearing standards and the barsbeing secured to .the slide. ,member 5! by screws 69. A worm 68 disposedbetween the bearing standards 59-58 has its shaft 62 journaled in saidstandards, one end of this shaft having secured thereon one member 63 ofa universal joint drive connection, the other the worm with respect tothe worm ring gear 45, e

and for this purpose the T-bars 59-59 are provided at their under sideswith posts Ill and H, respectively, to which springs 12 and 13 areconnected at one end, the other ends of these springs being connected toa post It secured tothe underside of the base plate 13 between theT-slots 56-56, and which springs normally tend to pull the slide 51 andthe worm gear carried thereon out of engagement with the worm ring gear45.

For the purpose of engaging the worm with the worm ring gear a cam lever15 is pivotally mounted by a shouldered cap screw I6 upon the base 13between the T-slots 56-56, and which upon being pulled outwardly fromthe position shown in Fig. 2 will have its cam surface 'II engaged witha bearing portion 18 upon the slide plate 51, and will force the slideplate inwardly, meshing the worm 6| with the worm ring gear 46, in whichposition the slide and worm are retained by means of an automaticlatching mechanism, the cam lever 15 being returned, upon release, toits normal disengaged position by means of a spring I9.

The automatic'l atching means conslstsof a supporting block secured byscrews 8! to the base plate Hand provided in its upper side with aT-slot 82 in which there is slidably engaged a locking bolt 99, the'noseend of whichis adapted to engage a locking recess 84in,the bearingstandard 58, the bolt being normally pressed in projecting direction bymeans of a spring .85

through which connection the spring exertsprojecting pressure upon thebolt, so that when the recess 84 comes into register with the bolt asthe slide' 51 is moved inwardly tl'Ye bolt automatically engages therecess and locks the worm in position. The lever 81 has secured upon oneedge a bar 9| which projects outwardly to provide a handle for manuallydisengaging the bolt when desired. The inner end of the lever t? has aninclined face 81 disposed in the path-of the pin 50 carried by the wormgear, so that by adjusting the degree of projection of the pin the pointwhere it engages the face 81 may be varied to thereby secure fineaccuracy in the stopping point.

It willbe'under'stood that when the bolt is disengaged from the recess84 the worm M will be withdrawn from engagement with the worm ring gear45 through the outward pull of the springs 12 and I3, and suchdisengagement occurs automatically when the ring gear is rotated inclockwise direction to a point where the pin 59 engages the face 9! andthrough the swinging of the lever 91 withdraws the locking bolt, thisaction occurring at a predetermined point determined by theending of thewinding operation. The bolt may also be manually withdrawn when geslredby means of the handle end of the bar As before pointed out the machineis primarily intended for the winding of wire or the like about a solidcontinuous core, and especially the'winding of wire about the ceramicring or core of a rheostat, such ring or core'A and 'wire winding Bbeing shown in Fig. 20. This ring is rotatably supported upon the post26 and is clampingly connected to the worm ring gear 4550 that as thering gear is rotated the ring A will be rotated with it. The support forthe ring A consists, as shown in Figs. 4, 5, 14 and 15, of a circularpiate slot 29 of the post 26, provided with an outwardly projectingperipheral, flange 94 spaced from the upper surface of the post 26, andprovided adjacent its inner periphery with a platform portion 95 havinga series of radially disposed bearing recesses 96 in whieh anti-frictionrollers 91 are engaged and secured against longitudinal movement bymeans of set screws 98 engaged in an The upper surface of the. support92 is provided with an annular recess lfll in which a guide roller ofthe clamping means moves, as will presently more fully appear.

In axial alignment with the shaft 23I and in spaced relation theretothere is secured in the bored end of the shaft I91 a driving shaft 236upon which a clutch collar 231 is slidably connected by means of aspline 238, this clutch collar having clutch teeth 239 at one endopposed to the clutch teeth 235, and having a bore 240 which forms withthe bore of the clutch member 234 a pocket in which is disposed ahelical spring 24I which normally exerts pressure to separate the clutchteeth from each other.

The clutch collar 234 is provided with an annular groove 242 engaged byrollers 243--243 mounted in the yoke portion 244 of a clutch engagingand automatic throw out lever 245 which is pivotally mounted at itslower end by means of a shouldered'cap screw 246 upon a block portion241 secured upon the base plate I2. Upon the block 241 a locking pawl248 is pivotally mounted by means of a shouldered cap screw 249 and isprovided at one end with a tapered locking tooth 250 adapted in thelocked position to engage a tapered hole 25I provided in the lever 245,being held in engagement with this tapered hole by means of a spring 252tied between a pin 253 provided upon the locking pin and a pin 254provided upon the block 241,

The locking pawl is in the form of a bellcrank lever, and at its outerend is pivotally connected by means of a shouldered cap screw 255 to oneend of a rod 256, which extends through a slot 251 in the vertical wallportion I4 of the base, see Figures 4 and 8, and is pivotally connectedat its upwardly ofiset other end 258 to the slidable support of the worm6|, this connection being preferably made by means of the pin 10 towhich one end of the spring 12 is connected.

It will thus be seen that the shuttle driving clutch which is shownengaged in Figs. 10 to 13 will be automatically engaged upon manualengagement of the worm 6I with the gear 45 through the cammingengagement of the tooth 250 with the slot 25 I and will be automaticallydisengaged upon either manual or automatic disengagement of the worm 6|from the worm ring gear 45, the forward movement of the worm support asthe worm is disengaged pulling the rod 256 and causing the locking pawl248 to turn and disengage its locking tooth 250 from the lever 245,whereupon the spring 24I presses the clutch collar 231 to the left, asseen in Figs. 10 and 12, and disengages the clutch teeth 239 from theclutch teeth 235,

thereby stopping the wire winding shuttle simul-' taneously with thestopping of the rotation of the ring-A.

-Between the drive shaft I96 of the variable power unit and the shaft 68for driving the worm (ii the changeable gear means is provided forimparting power from the shaft I98 to the shaft 65, such gear means alsobeing arranged to drive respooling mechanism mounted in relationthereto. The shaft I96 has keyed in its bored end one end of a shaft259, the other end of which is journaled in a bearing standard 260mounted upon the left hand edge of the base plate I3, a collar 26I beingkeyed upon the projecting end of the shaft adjacent the bearingstandard. At an intermediate point the shaft 259 is journaled in abearing standard 262 mounted upon the base plate I2, and between thestandards 262 and 250 there are keyed upon the shaft 259 a bevel gear263 and a spur gear 264, a spacing collar 265 being disposed between thespur gear 244 and the bearing standard 260.

The bevel gear 263 meshes with a bevel gear 266 keyed upon the end of aninclined shaft 261, journaled in spaced bearing portions 269 and 269 ofa bearing standard 210 mounted upon the base plate I2, a worm 21I beingsecured upon the shaft 251 between the bearing portions 266 and 269, anda retaining collar 212 being secured upon the lower projected end of theshaft.

The worm 21I meshes with a worm gear 213 loosely mounted upon a shaft214, and adapted to be connected thereto to drive it by slidable keymeans presently to be more fully described, the shaft being-journaled atone end in a bearing standard 215 mounted upon the base plate I2 and 7at its other end in a bearing standard 218 mounted upon the left handedge of the base plate l3, this end of the shaft having a projectingreduced diameter extremity 211, towhich is keyed one i member 218 of auniversal joint driving connection, theother member 219 of which isslidably splined to the shaft 85.

The spur gear 284 meshes with a spur gear 288 also loosely mounted uponthe shaft 284 and 8 adapted to be connected thereto to drive it by meansof the sliding key, presently to be more fully described, this spur gear288 having rigidly connected to it a spur gear 28| secured by pins 282,and the spurgear 28| having-rigidly con- 8 nected to it a smallerdiameter spur gear 283 secured by pins 284, the gears-288, 28| and 283adapted to rotate as a unit and the gears 28| and 283 adapted, as willhereinafter more fully appear, to drive the respooling mechanism. Aspacing collar 2851s disposed upon the shaft 214 between the worm gear-213 and the bearing standard 215. The portion of the shaft 214 extendingfrom within the spur gear 288 to the end of the shaft journaled in thebearing standard 21s is provided with a cylindrical bore288 and there isa longitudinal slot 281 in the shaft extending the length of the boreand communicating with it.

A slide rod 288 is engaged in the bore 288 and has a projected key 289secured in its end, which key engages the slot 281 and projects intoengagement with a slot 290 in the hub of the gear 288, in one position,and in a slot 29| in the hub of the worm gear 213, in another position,it

' being understood that in these respective positions the spur gear 288and the worm gear 213 are individually keyed to the shaft 214 to driveit, the other gear running idle. gne rod 288 projects through a passage292 I0. provided in a plate 293 secured by screws 294 to the bearingstandard 215 and it is provided upon its end with a hand wheel 295. Apair of spaced annulargrooves 298 and 291 are provided in'the rod 288,and one or the other of these'grooves,

[3 depending upon the position of adjustment of the key 289, is engagedby a pair-of yieldable retaining balls 288-298 disposed in passages299-299 in the plate 293 and pressed toward the rod 288 by means ofsprings 380-308, and thus releas- 30 ably retain the rod in one or theother. of its operative positions. As will be clear from Fig. '1 the keyis in engagement with the gear 288 when the rod 288 is in position tohave the groovei298 engaged by the balls 299-499, and when the rod 55 ispulled out to engage the balls with the groove 291 the key is. inengagement with the. worm" gear 213. By this arrangement the worm 8| fordriving the ring 45 may 'be' selectively driven, either by the wormgear-213 or the spur gear 280. 30 Upon the base plate |2, forwardly ofthe shaft 214 and the gears carried thereby, there is secured abearingstandard 38l, in which is-journaled a spool winding shaft 382,this shaft having secured thereon a small diameter spur gear 55 888 inalignment with the large diameter spur gear "I and a large diameterspurgear 304 in alignment with the small diameter spur gear 283, the endof the shaft projecting beyond the hub of the gear 384 and being securedtothe spindle 70 888 of an automatic counting device 388 mounted uponthe base plate l8, the counting device being for the purpose of keepingrecord of the number of turns of wire wound upon the spool.

spool winding-M882 is adapted to be 70 driven either by the gear "I or.the gear 233,

and for purpose a pair of clutch arms 381 and 808 are pivotally mounteduponstud shafts 309 and 3|8 projecting at each side of a bearingstandard 3| I mounted upon the base I2. I The arm 381 has a spur gear3|2 mounted thereon by 5 means of a shouldered cap screw 3| 3 and isadapted to mesh with the'spurgears 28| and-303 in its operativeposition, as shown in Fig. 8, while the arm 308 has a spur gear 3mounted thereon by means of a shouldered cap screw 3|5, and is 10adapted in the operative positionof the arm to mesh with the spur gears283 and 384, it being understood that. only one of the arms is inoperative position at one time. As shown in Fig. 8

the arm 381 is in operative position and the arm 1 308 is in inoperativeposition, the latter being dropped into engagement with the base platel2 in this inoperative position and being raised from the base plate inthe operative position.

Handles M8 and 3|1 are respectively provided 2 upon the forward ends ofthe arms 381 and 388, to. facilitate operating them and the arms are,respectively provided near their forward ends with holes 3| 8 and 3 I 9,with which a slidable locking bar 328, mounted in a block 32| secured tothe bracket portion I8 of the base I2 is adapted to engage, this rodclearing the upper surface of the lowered arm 388 when it is engagedwith the hole 3|8 of the arm, 381. The locking rod 328 is adapted to besecured in locked position by a set screw 322 provided in the block 32|.It will be understood. that, depending upon which pf the arms 381 and388 is in operative position, the spool winding shaft will be driven byeither one or the other of the gears 28| and 283.v

Upon the left hand end of the shaft 382 there is provided a spindle 323upon which the spool I84 is engaged and retained by a collar 324, it

being understood that this spool can be respooled with wire while asimilar spool; I84 is in operation 40 upon the shuttle I84, so that therespooling operation may be carried on simultaneously withthe winding ofthe ring A. Upon the forward surface of the bearing standard '38| thereis provided an angle bracket 325,

which is hingedly mounted at itslower end by means of a hinge pin 326having bearing in projectingbearing portions. 321321 formed upon thelower end of'the bearing standard 38|,' this bracket adapted to besecured in raised opera- 5 tive' position by means of a screw 328,engaged in the bearing standard 32| and extended through a vertical slot329 in thevertical portion of the bracket, a wing-head 330 beingprovided at the outer end of the screw which is adapted to pass,

freely through the slot in its vertical position and I to lockinglyengage the surface of the bracket in its horizontal position, so that bymoving the screw to bring its head into the vertical position thebracket. may; when not in use,', be swungdownwardly out of the way;

Mounted upon thebracket m is a block :32

A knurled head 349is provided upon the end of the retractable pin 346 for the purpose ofdisengaging the pin from the spool to permit removal of the, spool andmounting of a new spool in .its place.

As shown in Figs. 1 to 5, and Figs. l4 and 15, the machine is arrangedto wind wire upon a ring of relatively small diameter. However, themachine'is adapted by adjustment and interchangeability oi parts to thewinding of a ring having a diameter substantially as large as theoutside diameter .of the flange 28 of the post 26, and also to windrings of any diameter between the small diameter ring as illustrated inFig. 14 and the large diameter ring as illustrated in Fig. 18,

In Figs. 16 and 17 I have illustrated a replacement ring support 92substantially similar in construction to the ring support 92 but oflarger diameter, this support being suitable for the support of rings ofsizes of an intermediate range of diameters between the minimum andmaximum limits of the machine. This support 92', like the support 92,has a radial slot 93", a flange 94", a platform support 95 provided withradial roller recesses 96 and cylindrical rollers 31 rotatably .mountedtherein and provided with conical rollers Hi0 at their inner ends. Anannular recess IIlI is provided for engagement of the roller I 05* ofthe ring clamping block I03, this block being,pro-

vided at its inner end with a recess II I4 for engaging about theperiphery of the ring support, and being provided at its inner end abovethe ring support withoutwardly projecting apertured flanges lin -I01through which are slidably engaged horizontally movable clamping pinsIOB I08, adapted to engage, the horizontal holes b of the'ring, therearward ends of these pins being mounted in a' cross bar I03 movable ina slot I III of the block. n

The clamping head I I5 is secured to the upper. side of the blockI03*'by .a set screw H5. The clamping head I I5 and its detailsare'similar to the clamping head I I5, except for slight variations inthe dimensions, so 'that a further detail description of these parts isnot deemed necessary. A vertically disposed. downwardly projectingsquare shank 35ll is secured to the block I03, this shank being in thesame relative position with respect to the central vertical axis.of thesupport as the shank I25 of .the clamping member I03, so that when thering support 32 is mounted in place upon the post 25- the shank 350 willengage the square hole 54 of the arm 52. A handle ing member Ill3 formanually rotating the rin to any desired position. v

vided at their inner ends with conical rollers I00". The ring clampingmember I03" is provided with a recessed inner end I04 for engaging aboutthe periphery of the ring support, and is provided at its inner endabove the ring support vwith outwardly projecting apertured flanges N-I01 through which are slidably engaged the horizontally movable pinsfilt -I03 for en gaging the holes b of the ring, these pins beingsecured at their inner ends to a cross bar III!" slidable in a slot H00! the block I03". The clamping head 5 is secured to the upper side ofthe block I03 by a set screw H6, and except for slight variations in thedimensions is similar in detail to the clamping heads I I5 and I I5. The1 block I03 is provided at its under side with a dependingsquare shank352, also disposed in the same relative position with respect to thecentral axis of the support 92 as the shank I25 with respect to the axisof the central support 92, and is adapted to engage the square hole 54of the arm 52. A handle 353 is secured to the rearward side of theclamping member I03 for manually rotating the ring to any desiredposition.

In the use of the ring supporting and clamping structures shown in Figs.16 and 17, and 18 and 19, interchangeable replacement clamping arms I33are mounted in place upon the support I29, these arms being relativelyshorter than the clamping roller supporting shafts I31-I31 spaced widerapart, so as properly to engage the particular ring being wound. Asthese replacement clamping arms I33 are of the same structure as theclamping arm I33, shown in Fig. 4, except for length and width,theirillustration in the drawings is not deemed necessary for the clearunderstanding of the invention.

In arranging the machine for winding diflerent diameter wires it will beunderstood from the foregoing that the central vertical axis of the ringA being wound remains constant and is'coincident to the central axis ofthe post 26, but that the position of the body of the ring varies withrespectto the central vertical axis, so that the wire winding shuttlemust be shifted in order to bring its center into line with the centerof the circumferential body of the ring. It is for this purpose that theblock I5I. is mounted for sliding movement in the gibs 35-36. When thesupports 32 and 92 replace the support 32 the slide block I5 I and theshuttle mechanism carried thereby, is simply moved rearwardly, beingprovided in its upper surface with three pockets 310, 3" and 312 in oneof which a locking pin-313, disposed in a hole 314 in the cover plate3|, is engaged to fix the position of adjustment of the slide'block NH.The universal joint connections 1 between the shaft I14 and the shaft23I, as well as the extensibility of the connection provided by thesplined slidable connection of the shaft I32 with the universal jointmember I3I, permits the sliding adjustment of the slide block I5Iwithout disturbing the driving relation. The same is true I support forthe worm -GI and the shaft 314.

The operation of the machine is as follows:

The spool or bbbbin I8I, containing the wire suitable for theparticularitype of ring to be wound, isplaced' upon the shuttle gearI54, the 70 spool having previously been wound by the spoolingmechanism. The shuttle is rotated by means of the hand wheel) to a pointwhere the slot lit registers with they slot I32 of the support Ill, andthe ring A, and to which one end of the wire B, which has previouslybeen carried about the tension and guide rollers, has been secured atone end by threading it into a suitable hole provided in the ring forthis purpose. is placed upon the ring supporting member 32 by insertingit through the slots I08 and I82 so that the ring surrounds the shuttle.

' looked, as well as by connecting either the spur gear 280 or the worm213 to the shaft 214 by shifting of thekey rod 280 by means of thehandle 295. Also the desired tension for the particular wire ispredetermined by adjustment of the calibrated tension dial I 88. Theparticular speed is-also predetermined prior to starting the machine, byengaging the clutch 202 with one or the other of the pulleys 201 and208, it being understood that these preliminary adjustments aredetermined by the particular type of ringbeing wound and characteristicsof the wire, a small gauge easily bendable wire being wound :vtr adifferent speed from a heavy relatively stifl' e. r The machine is thenstarted by engaging the worm 8| with the worm ring gear by means of thehand lever 15, the shuttle driving clutch collar 23'! beingsimultaneously engaged by means of the tie-rod 258 which upon inwardmovement of the worm support is pushed to rotate the bell crank pawllever 248 in clockwise direction. causing the tapered pawl tooth 250 toenter the slot 25I of the clutch operating lever and through the cammingaction between the tooth and the slot swinging the lever to clutchengaging position.

.of the lever '9 I The shuttle now rotates about the rotating ringwinding the wire thereon, and this continues until the winding .iscompleted. At the predetermined winding completion point the pin 50engages the arm 9| tripping the lever 81 and disengaging the lockingbolt 83 from the recess 84',

whereupon the released worm gear support is drawn outwardly by means ofthe springs 12 and I3. Simultaneously therewith the shuttle drivingclutch is released through the action of the tie-rod 256, the pullimparted thereto through the movement of the worm support rotating thebell-crank-pawl'lever 248 in clockwise direction vand disengaging itstooth 250 from the slot 25I', whereuponthe spring-2M forces the clutchcollar' 23'! and its teeth 23! out of engagement with the clutch member2 and its teeth 235.

The wire is then out between the ring and the spool, and the wound ringremoved through the registering slots I86 and I62,-the holding arm' I33having first been released and swung to its inoperative position uponthe support I50. The

operator then pulls the clamping unit back to the starting place bymeans of the handle I28,

quently the pitch of the winding; by adjustment of the power unit,suchadju'stment beingshown on the dial 20L In winding larger diameterrings than that shown in Figs. 1 to l5 the. ring suppo t 92 and theclamping block I03 are replaced by the ring support32' and clampingblock I03, as shown.

in Figs. 15 and 17, or by the ring support ring 02'' and the clampingblock I03 as shown in Figs. 18 and 19, and the shuttle is shifted tobring its center into line with the circumferential center of the ringto be wound, the shiftable shuttle support being secured inits shiftedposition by engagement of; the locking pm 313 with-one or the other ofthe pockets 3' and 312.
